To 1/// whom it m/m CUIMJGII'L.

Be it known that 1, llARVEYLElUY, a citizen of the United States, residing at arring ton, in the county of Foster, 51 ate of North Dakota, have invented certain new and use l'ul improvements in Wagon-Uilers; and ldo hereby declare the following to be a lull, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation generally to devices for luhriea.ing'surlaees that it. is necessary to keep oiled, and it has special reference to luhrieators for wagon-axles.

It is the object of the invention to provide improvements in luhricators for vehiclewheels that will enhance their ellieiency by simplil'ying their constrtwtion and mode of operation, making them less expensive to inanulacttn'e, giving less trouble to apply,

and also inakingthein entirely certain in their operations, so that they can be relied upon t. o perform their functions in point of time ol' delivery of the lulu'icant, amount dclivered, (X10.

The invention consists of a reservoir for the lubricant, a suitable duet for conveying it to the sur'laces to be luln'n'ated, and a apart of thili Speellication, and then he pointout with particularity in the suh oincd claun.

()l' the said drawings, l igure 1 is a central sectional side el ,valion ol' .in invtrition. Fig. 2 an end view of certain p: ts, indicating a way of applying the device to a wagon.

The same figures of reference designate the same parts or features, as the case may be, wherever they occur.

in the drawings, 5 designates the grease cup or oil-reservoir, which may be arranged. horizontally or vtn'ticallv, as circunistances may dictate as best. in the said. reservoir there is arranged a plunger 6, so as to have a perfect lit therein, and to this end it may he composed oi two disks 7 7, ol l.lll1 1 5tt30l of a diameter that will allow their free- .lriovcinent in the reservoir, with a disk oi." leather 8 or similar substance clamped between them to insure a perfect lit. The outer surface of the margin of one end of the reservoir is screwthreadcd, as at 9, so as to enable the flange 10 of the cap 11 to be screwed on the reservoir with. an oil-tight fit.

An extornally-screw-threaded stcmzilZ ex tends through the internally-screW-threaded sleeve-hub 13 of the toothed wheel 14 outside of the cap 11, which gear 14 is engaged by a cog-wheel .15, keyed or otherwise secured to the outer end of the counter-shaft 16, supported in suitable hearings connected with the reservoir. The inner end of the stem .12

rests on the center of the plunger 6, which i an opening formed in the plunger and is engaged in a threaded socket formed in the stem end. The shaft 16 has a sprocket-wheel 18 secured on its outer end, the radially-projectv ing teeth or pins on which are adapted to be atlptst, and keep in order than hereto'lore,

engaged by a laterally-projecting pin from the hub of the wagon-wheel at each revolution of the latter and rotated to a certain extent. This rotation of the sprocket-wheel turns the shaft 16 to the same extent, which operates the shaft 12, through the intervention of the cog-wheels 14 and 15, moving the plunger 6 inward to a sufficient extent to force a small amount of the lubricant in the reservoir. through the duct 19, leading to the surfaces (not shown) to be lubricated. A spring 20 surrounds the outer end. of the s raft 16 between the hub of the sprocketxvheel 18 and the outer bearing 21 of said shaft. This sprin is of just the right length to keep the whee well up to position and allow the shaft to be pressed back to permit the lid tobe removed to iill the'cup or reser- VUll. v

in Fig. 2 the reservoir or cup 5 is shown as provided with a base 22, to which are s'ecured by screws 23 clamping-plates 2 1, hanged, as at 25, to receive a; clampingscrew 26, so that the device may be clamped on the axle or other suitable part of the wagon. In addition to the clamps screws 27 may also be. used, if desired.

it is to be noted that, as stated at the outset, the device is so organized as to be certain in its mode of operation,-and there being relatively few parts it is notliable to get out of order or to require unnecessary time to keep it in order. s

W hat is claimed as the invcntioni A lubricator h r wagonaxles s in eo1nbination",.lt grease or oil cylihdciif Yided with a plunger, a cap, an externallytln'eaded stem extended through tlie cap, an internally-threaded sleeve in the cap s1irrounding the stem, :1 co -wheel on the sleeve, bearings secured to said cylinder, a countershaft journaled in said bearings and extending at one ,end beyond its bearing, a sprocket wheel mountscl on said extended end, a

spring surrounding the countershaft and in- 'tergosed between-the sprocket-Wheel and the sai outer bearing, a cog-wheel on the oppothe co -wheel on said sleeve a basevc'bnnected wit 1 said cylinder, and detachable clamps 'Securezlto th'lmse for attaching the, base to a part of the wagon or othelfcontrivanee'. 1 lntcstimony whereuf 1i affix my signature 1 in presence of two witnesses, v v
